channel balance 27 4

Hello,

We'd be happy to help but we would need to see photos of an undamaged balance removed from your window, including the end attachments and any number stamped on the metal channel. Thank you!

With this combination of attachments, you could have either an S380-28 or S385-28 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need 2740 spring strength options for your replacement balances.

Thank you and let us know if you have any other questions or concerns.
